In 2008 this camera is the best choice for amateurs who desire a
full frame 24x36mm sensor at a reasonable price. I've found on the
market for less than 1500€ and I've modified it with the
Baader ACF
filter,
thanks to my friend Gianluigi. The first impressions from two nights on
a dark sky are really good, with great results even with ambient
temperatures (+15 to +20 °C).
The characteristics and performances are so well known that is unuseful
to list them here.
